How do I access the SD card files in a M241 / M251 controller?

It is not possible to access the SD card file from the SoMachine File Manager.. The File manager can only access the files in the internal memory but not the SD card. To access the SD card file you must use an FTP client tool such FileZilla.
The login and password are both USER (All capital letters)
